Low power 2 W @ 8 ohm, 4 - 16 ohm usable simple, class A SE - any recommendations?

I am terrible at finishing electronic projects. If it is not super simple or a PCB available, it usually never gets past looking at the schematic stage🙂 I have some large heatsinks and MOSFETs and resistors, so I will start experimenting with FAOW/MOFO style amplifiers before I get to something more advanced.

I have some 4 mH air core inductors as well, while on the low side, maybe these could be large enough for MF/HF use.

Actually, the coil (4 mH) was intended to be a part of the passive crossover high pass. Together with a 22 uF capacitor. If I used the inductor as load and capacitor as output, would both components work as a part of the crossover? The capacitor should - but I am not so sure about the inductor when serving as a load to the follower.
